| + 251092 [gwtmp01 mac.] If Ruby is 100% OOP, then what is Smalltalk?
| | 251166 [shortcutter ] Probably more in the 120% area. ;-)
| | 251167 [ecomba mac.c] LOL... That makes Smalltalk somehow metaphysical... It's like saying

+ 251089 [codeblogger ] You don't need to defend yourself. Tell your friend he hasn't understood OOP
+ 251090 [gwtmp01 mac.] Just redefine the meaning of 100%, that should work.
| 251120 [sam powersou] And more importantly, what value would that bring?
+ 251094 [debertin gma] Well, as others have said, it's a stupid thing to argue about.
